Abstract

Introduction: Hyperphosphatemic Familial Tumoral Calcinosis (HFTC) is a rare autosomal recessive metabolic disorder characterized by abnormal phosphate regulation and soft tissue calcifications. Early diagnosis is crucial for optimal management to prevent complications. Case Presentation: A one-year-old child presented with intermittent fevers and a gluteal mass. Ultrasound revealed a calcified abscess, and biopsy confirmed a pseudocyst. Further workup identified elevated blood calcium, phosphorus, and neutropenia. The patient was ultimately diagnosed with HFTC. Discussion: Early diagnosis of HFTC is challenging due to the rarity of the disease and the potential for non-specific initial symptoms. This case highlights the importance of considering HFTC in the differential diagnosis for a young child with unexplained soft tissue masses or skeletal abnormalities, even outside the usual age range. Conclusions: This case report emphasizes the need for a high index of suspicion for HFTC in pediatric patients with suggestive clinical features, regardless of age. Early diagnosis and prompt intervention are essential to improve long-term outcomes and prevent complications. © 2024, Shakiba et al.
